More than 65535 vertices in a single ssgLeaf is "A Bad Thing" anyway because
the entire leaf either is or isn't passed on to OpenGL...there is no field
of view culling *within* an ssgLeaf.

If your model has nodes as large as that, it's not going to render efficiently
anyway.

We *could* automatically split large leaf nodes into a branch and multiple
leaves - but that's a *LOT* of hassle and since rather few models would
ever make use of it...and those models are already doomed to fairly poor
performance...I think we should just flag a nice error message and abort.

If someone passionately wants to write all the needed code to split objects
into multiple leaf nodes then we should certainly accept it...but I wouldn't
be very excited about writing it myself.
